I think it's the mystery of it all that brings all these interesting theories out. And, I personally think (with no information truly to go on) it's likely to be a strange set of unique occurrences/circumstances that will be discovered when the aircraft is finally located.

Why would China ever rely on a foreign civilian airline to deliver "secret cargo? "What kind of cargo could Malaysia possibly have that would need to be physically transported and that China couldn't just get on their own?

- The Daily Star is a British tabloid. They're not exactly known for going out of their way to verify sensational stories, and have been successfully sued for libel in the past. Doesn't seem like they're as bad as the Daily Mail or anything, but them being the source of a story doesn't exactly lend credibility. I think it's notable that, as all the comments there pointed out, they don't provide coordinates, which would be trivial to obtain if it was found in Google Earth.

- Google Earth is not designed for viewing pictures of the ocean. There is only a tiny patch of ocean that is ever photographed in the areas that could reasonably be considered 16 kilometers "south" of Round Island, and it's always at extraordinarily low resolution. I couldn't find the exact spot they're talking about, in no small part because the area doesn't appear to have been photographed on 4/19/14 like the image claims, but I did find numerous other shapes that could pass for aircraft just as well in different places in that tiny window in photographs from 2009 to May 2014. They're clouds and wave crests, much like that appears to be. To see a plane, even one of that size, at that scale in Google Earth, you have to zoom in *very* close, at which point the low-res image of the ocean just turns into squares. You don't get anything near that clear of an image at the zoom level required to for a plane to be that large.

- I assume he chooses to phrase it as "16 kilometers south of Round Island" because that sounds a lot better than "6 kilometers north of Mauritius", which is home to just over a million people. The area is also near a major Indian Ocean shipping lane, and all ships going through the area would have had to miss the plane despite the depth being just 150-450 feet in the area and the water apparently being so clear that you can see the floor from a satellite.

I spent entirely too much time looking at compressed images of the Mauritian coast just now.

"‘Four years on, we are none the wiser’: Reason MH370 hasn’t been found
THE MH370 report exposes a series of mistakes that hampered the search — and one crucial failure which did even more damage."

THE “final report” into missing Malaysia Airlines Flight 370 confirms the theory that someone deliberately diverted the plane from its course before it mysteriously vanished.

It recounts a series of mistakes that delayed the search and rescue operation — and one crucial failure of a system that could have immediately located the lost MH370.

The aircraft was fitted with four Emergency Locator Transmitters, in accordance with regulation, but every one of them failed, the independent report states.

Their batteries were within their expiry dates but no search and rescue agencies or other planes in the area reported receiving a distress signal.

“There have been reported difficulties with the transmission of ELT signals if an aircraft enters the water,” reads the report released on Monday. “The ELT does not activate, or the transmission is ineffective as a result of being submerged under water.”

This is a nice, informative video that summarizes everything we definitely know regarding the flight. With so many different conspiracy theories and contradicting reports, I honestly wasn't sure what we actually knew about the flight and what was just random guessing.
